i have an 8 week old plant and the lower fan leaves are turning brown and curling at the tips but all the top fan leaves are really healthy, any advice to give would be great
i am new to growing and still learning
^Agreed. It could also be a low-light situation. Plants will start to shed their lowest leaves, when they get too shaded, which is common, when growing indoors.
On second thought,...they usually turn yellow and drop off, not brown and crispy. Probably lack of food, whether it be PH, or not enough in the soil.
